Too true :) Seems I didn't, or was taught wrongly.
But then, while you teach me better:
What about bitshifts? Does the compiler also adapt the direction of the
command? I suppose it is already defined in terms of MSB and LSB, with MSB
being left to the LSB by definition? (I guess it works this way as I am on a
Little-Endian machine and it works :)
So no IF ELSE ENDIF needed?
Thanks for some education :)
